To all whom it may concern:

Be it known that I, AANEN TRAVLAND, a citizen of the United States,residing at I'Ioffman, inthe county of Grant, State of Minnesota, haveinvented certain new and useful Improvements in Bicycle-Boats; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to new and useful improvements in boats, and ithas particular reference to a boat propelled by foot power and of thetype known as marine velocipedes.

ln connection with a boat of the above type the invention aims as aprimary object to provide a novel construction, combination andarrangement of parts, the details of which will appear in the course ofthe following description, in which reference is had to the accompanyingdrawings forming a part of this specification like characters ofreference designating similar parts throughout the several views,wherein:

Figure I is a top plan view of a boat constructed in accordance with thepresent invention, parts being broken away to more clearly show thefeatures of construction. lligA 2 is a side elevation thereof, the coverfor the paddle wheel. being broken away at one side. Fig. 3 is avertical transverse section on the line 3-3- of Fig. l.. Fig. 4 is acentral longitudinal section thereof. Fig. 5 is a detailed perspectiveview illustrating the housings for the paddle wheels.

Referring specifically to the accompanying drawings the numeral ldesignates the hull including the deck 2, and the raised sides 3, therudder I being secured at the stern in the usual manner. Centrally ofthe deck 2 are mounted alined bracket bearings 5 in which is journaled atransverse power shaft 6, the latter carrying on its projecting ends thepedals 7 and between said bearings a sprocket wheel S. Rearwardly oftheshaft 6 is a transverse shaft 9, journaled in bracket bearings l0 andprojecting on each side beyond the sides of the boat. The shaft 9 has acentrally located sprocket ll which is driven from the sprocket 8 by achain l2. On its projecting ends the shaft 9 carries sprocket wheels l3which serve by means of chains 14 to drive the transverse propellershafts l5, the latter carrying sprockets 16 over which the chains 14 aretrained. The shafts l5 are journaled in antifriction bearings in thehull l and in curved housings I7 secured to said hull by means offastening devices engaged through offset flanges 18. rIhe housings I7are open at their lower ends and inclose the paddle wheels 19 fast onthe respective shafts and likewise the sprockets I6, said housingshaving openings 20 in their offset portions to allow of the movement ofthe chains 14 therethrough.

The steering mechanism includes a vertical rock shaft 2l journaled inbearings in the deck 2, which at its upper end carries the handle bars22 and at a point above the deck 2 carries the oppositely extending arms23, the latter at their outer ends having connection with cables 24which extend rearwardly the length of the deck and are trained oversuitably supported guide pulleys 25 and 26 and at their ends areconnected to the rudder 4 on each side thereof.

It is preferred to inclose the shaft 9 and the parts directly associatedtherewith in a housing 27, which supports a forwardly projecting seat 28and which has openings 29 in its front wall to allow of the movement ofthe chain l2 therethrough.

It will be understood that the shaft G through the connections describeddrives the paddle wheels I9 in either direction and that the position ofthe rudder is controlled by movement of the vertical rock shaft 2l. i

From the foregoing description it will be seen that simple and efficientmeans are provided for accomplishing the objects of the invention but,while thev elements herein shown and described are well adapted to servethe functions set forth it is obvious that various minor changes may bemade in the proportions, shape and arrangement of the several partswithout departing from the spirit and scope of the invention as definedin the appended claimsA What is Claimed, is:

A boat of the type set forth, comprising the combination with the hulland its deck, of a pedal operated power shaft supported on said deck, atransverse shaft rearwardly of said power shaft, and driven therefrom,sprocket wheels located at the ends of said transverse shaft, curvedhousings having offset iianges secured to the hull at opposite sidesthereof and open at their bottoms, transverse shafts hav-ingtheir' endsjournaled in said housings and in said hull, said housings being formedwith spaced openings, sprocket wheels provided on said respective lastnamed transverse shafts, chains connecting said end sprockets with saidlast named sprockets and working through said openings, and paddlewheels fast on said last named shafts.

In testimony whereof, I affix my signature, in presence of twowitnesses.

AANEN TRAVLAND.
